Cancer causes unrestrained cellular proliferation and growth, and in some cases, cancer cells can hide from or compromise the body’s immune system, which is designed to fight off infections and illnesses. This is one of many reasons why cancer is such a devastating and dangerous disease.
One of the rising treatment methods for cancer, however, is immunotherapy, a type of biological therapy. It is used to restore the immune system or greatly boost its normal functionality. Immunotherapy can introduce new elements to the body’s immune system or stimulate what is already there to help the immune system better destroy cancer cells. It can slow and stop the growth and spread of cancer, as well as effectively deliver radiation or chemotherapy to the cancer cells directly.
Methods Of Immunotherapy
Patients can receive immunotherapy in approximately four different ways. The two most common methods are oral, in which the patient swallows a pill, and intravenously, where the doctor administers immunotherapy through a needle inserted into one of the patient’s veins. There are also topical immunotherapies, which is where the patient rubs cream into their skin. Topical treatment is usually for early stages of skin cancer. Finally, there is intravesical immunotherapy, where the treatment goes directly into the bladder (specifically used to treat bladder cancer).
